The last two paragraphs. I read them to say that the Texas SOS is saying she has been re-assured that the observers will abide by election laws. Reading between the lines then I take it to mean that they will given permission since they have agreed not to interfere. After all, Hillary sent her a letter.

They have agreed to abide by our laws.
They know and understand the consequences if they behave otherwise.
That is not a ‘cave’.
